In this research we propose a music composition system based on Twelve-tone Technique that is a music composition technique of the contemporary music, as the composition method by the computer. Twelve-tone Technique has the advantage that it is suitable for the composition of computer music because it is a technique to compose the music step by step. Making of the twelve-tone row, which is the first process of the Twelve-tone Technique, is an important process to determine the subject and atmosphere of the music. In this research, we design the fitness function based on the relation between the consonance interval and dissonant interval that are a part of general musical theory, and perform the automatic generation of twelve-tone row by searching the consonance tone row with GA. We constructed the simulator that generates twelve-tone rows and confirmed the effectiveness of this system by executing the comparison questionnaire of twelve-tone rows made by the simulator and human.
